Phosphors based on Ce:(Pb,Gd)3(Al,Ga)5O12 epitaxial films: synthesis, optical properties, application

Abstract

Ce-doped (Pb, Gd)3(Al, Ga)5O12 single crystalline garnet films were grown using liquid-phase epitaxy method from supercooled PbO–B2O3-based melt solutions on substrates from Gd3Ga5O12 and Gd3Al2.26Ga2.74O12 single crystals. Optical absorption and photo- and cathodoluminescent properties of these epitaxial garnet films were studied. Ce-doped (Pb, Gd)3(Al, Ga)5O12 garnet films can be used as a fast phosphor in the design of a PIF-01 electron-optical converter.
